Riddle

In my research on ancient writings, I have found a message that tells a hidden legend:

"Op sihoupi aco hipt usdusan petdovas, qsuqi tqimapden qsuceviupan, aco iyisdipv fotdoqmopen taen, tapv esdepe nupumevjusan. rao qsucevoupit qseivisoisapv iv i tqimapde ef raoicin iyiapv, fodapv ti eafowotti tatassan mophae ohpuve."

I have spent hours trying to decipher this message, and after analyzing the word patterns, I believe I have found a possible transformation system. It seems that the letters have been rearranged following a specific structure, and some characters might have been shifted within the alphabet. I am not entirely sure how it works, but I have managed to translate part of the message into Latin:

"In regione ubi gens orcorum nascitur, prope speluncam probationum, ubi exercent disciplinam suam, sunt arcana monolithorum."

One particular phrase caught my attention: Cave of Trials. This name appears to correspond to a known location on the map, which suggests that this message might contain a direct reference to it.

I still do not fully understand the exact meaning of some words, but I can confirm that "tqimapden" translates to speluncam and "nupumevjusan" becomes monolithorum. This suggests that the transformation follows a logical pattern, although its full structure remains a mystery to me.

If we manage to decipher the rest of the message, we might uncover a crucial clue for our quest. Now that we know the text appears to be Latin in its original form, you can continue the translation work and reveal its complete meaning.

May the echoes of the ancients illuminate your path, adventurers!
